Repeat Problem. but interchange εr1, and εr3

Problem

For the configuration shown in Fig., use transmission-line equations (or the Smith chart) to calculate the input impedance at z = −d for εr1, = 1, εr2 = 9, εr3 = 4, d = 1.2 m, and f = 50 MHz. Also determine the fraction of the incident average power density reflected by the structure. Assume all media are lossless and nonmagnetic.
